SLIDE HEAD GATE.

Application filed August 1, 1921.

To all whom it mayiconcern Be it known that we, KARL Jo'nAN THORSBY andRAYMOND CHARLES F onca, citizens of the United States, residing atOakland,

in the county of Alameda and State of California. have invented certainnewand useful Improvements in Slide Head Gates, of which the followingis a specification.

Our invention relates to that class of water-gates commonly known, fromtheir direction of movement, as slide-headgates. One object of ourinvention is to provide a gate which is simple and economical in itsmanufacture.

Another object is to provide a gate which may be shipped partlyassembled, and in v such manner as to eliminate crating and boxing, andwhich also may be attached to a pipe before leaving the factory, afeature in the installation of of great advantage the gate.

Another object is to provide a gate which may be easily put together andtaken apart by unskilled labor.

A still further object is to which is easy to operate and its functions.

With these objects in view, our'invention consists in the novelslide-headgate, which we shall hereinafter fully describe by referenceto the accompanying drawings in which provide a gate dependable inFigure 1 is a front elevation of our gate showing the cover, memberpartly elevated.

Figure 2 is a side view of the same, partly in section, on the line 2-2of Fig. 1. 4 F Figure 3 is a section on the line 33 of igure 4- is adetail showing a modification in the connection between the liftingmember and the gate cover.

Figure 5 is a front view of the gate cover and the gate seat-ringshowing these parts assembled ready for shipment.

Figure 6 is a top view'of Fig. 5.

Fig. 7 is a front elevation of our gate when made of rectangularcontour, adapted for attachment to a wall or bulkhead.

Figure 8 is a section on the line 8-8 of Figures 9 and 10 are detailedviews of the wedge-block 13.

' In the drawings like numerals indicate similar parts in the differentviews. The

1s, for convenience only,

i said wedge bloc-ks in position, which is the Serial No. 488,878.

gate seat-ring 1 is attached to a pipe 2 and shown riveted to pipe. 3 isthe gate cover. with a machine finished face 4, makes contact with asimilar machine finished face 5 on gate seat-ring 1.

hegate cover 3 is also provided with two wings 6, one on each side, saidwings having grooves or slots 7 (see Fig. 3). The grooves 7 engage guidemembers '8 which are, for convenience, shown as angle irons. The gateseat-ring 1 is provided with bosses 9 which project beyond the plane ofthe machine finished face 4 of the cover 3 in'such relation that whenthe guide members 8 are placed on the bosses 9, one leg of said members8 will fit in the slots 7 on thegate cover, as shown in Fig. 3.

'The guide members 8 and bosses 9 are provided with corresponding boltholes to receive bolts 10 and 11. Bolts 10 and 11 will, when screwedtight, keep the guide members 8 in a fixed relation togate cover 3.

he gate cover 3 is provided with wedge members 12 as shown in Figs. 2and 3. The wedge members 12 engage wedge blocks 13, and the relationbetween wedge members 12 and wedge blocks 13 is such as to press andhold the faces 4 and 5 tightly together when the gate cover 3 is in aclosed position. thereby making a watertight connection between the gateseat-ring 1 and the gate cover 3.

i The wedge blocks 13 are held in position by the clamping bolts 11,thereby dispensing with separate rivets or bolts to hold generalpractice. The wedge blocks 13 are provided with a lip 14 which engagesthe wedge members 12. Lips 14, as seen in Figs. 9 and 10, have the shapeof a double wedge which is symmetrically disposed on either side of thecenter of the bolt hole. The reason for this is to provide a wedge blockwhich may be used equally well on either side of the gate. therebyavoiding the necessity of having separate left \and right'members whichare liableto create confusion.

Another advantage is. that when the wedge blocks 13 become worn fromprolonged use, it is only necessary to loosen the bolts 11 and changethe left wedge block 105 over to the right, and vice versa.

The gate cover 3 is provided with a pocket- 15 which receives the. lowerend of the in the pocket 15 side of the means for operating the lifting1'0 The guide members8 are the clamping be cinched tightly againstabsolutely protected a radius concentric; to radius 17 on rod 16.

5 The beat end 19 may be inserted into pocket 15 by starting the rod inan inclined position, is'cleai*-ly' indicated by dotted lines, Fig. 2.After-the rod 16 is placed in a perpendicular position .*the bent end 19is confined and when the lifting ro 16 is being raised, the upper sideof the bent end 19 engages the tongue 18, thereby raising and openingthe gate cover 3, an

when the lifting'rod 16 is lowered. the under bent end-19 pushes againstthe bottom of the pocket15, thereby forcing the gate cover 3 down toaclosed position. Fig. 4 shows a slight modification of the pocket 15.in which a pin 24 takes the place of the 20 solid tongue 18.

The guide members 8 are extended to any suitable height and are providedwith a bridge or cross member 20. Cross member 20 acts as asuitablesupport gor the In the drawing Figs. 1 and 2, a handwheel 21 is,for convenience, shown as a suitable operating means, though a number ofother devices will work equally as well. I provided with stop bolts 22which are so placed as to act as 'stops against theprojections 23 ongate cover 3 when said gate cover 3 is raised to full opening, as shown'by the dotted line in 35 Fig. 1; thereby preventing the faces 4 and 5from becoming disengaged.

Figs. 5 and 6 show the main elements of the gate as these appear whenbeing shipped. The essential feature lies in the fact that bolts 11serve as a means for keeping the gate cover 3 securely against gateseat-ring 1. It will be noted that since the guide members 8 are removedand shipped separately, the wedge blocks 13 may the wedge members 12 bytightening up on the bolts 11.

The gate cover 3 is provided with a lug 25 located at its top edge. Abolt 26, Figs. 5 and 6, extends through the gate seat-ring 50 1 and thelug 25 for the purpose of preventing the gate cover3 from sliding out ofposition, if it should be subjected to blows or rough handling whilebeing shipped. It

faces 4 and 5 are will also be noted that the against any injury fromand thus the cover and seatreadily be shipped without rough handling,ring may very any crating or boxing, requiring only the one extra bolt26, as the other bolts 11 are the same as are used in the assembledgate.

in Figs. and 8 are shown a modified construction of our water gage, theopening being rectangular. -A flange 27 is 'provided for the purpose offastening the gate ring 1 to a wall or bulkhead. Ofcourse any other formor shape may be used and still be within the scope of this invention.

A slide-headgate comprising a gate seat-member; a reciprocative gatecovermember having a wedge; a wedge block coacting with the wedge of thecover-member; and a bolt connecting the wedge-block with the gateseat-member, adapted to tighten and hold the seat and cover memberstogether when packed for shipment.

A slide-headgate comprising a gate seat-member; a reciprocative gatecovermember having a wedge; a wedge block coacting with the wedge of thecover-memher; the gate seat-member, adapted to tighten and hold the seatand cover-members together when packedofor shipment, and a bolt fortemporarily connecting the upper a bolt connecting the wedge-block withcommon by a bolt to each boss; a gate covermember having side-wingsslidably grooved upon the guide members and havingwedges co-acting withthe wedge-blocks to effect a tight joint between the adjacent faces ofsaid cover-member and said "seat-member; and means for reciprocatingsaid covermember. 3 t

4. A slide-headgate comprising a gate seat member; a guide-membersecured to said seat-member; a reciprocative gate covermember slidablyfitted upon said guide; and a wedge block removably secured to theseatmember and co-act-ing with cover-member to make a tight-jointbetween the adjacent faces of the cover and seat members. said wedgeblock having complemental 'wedging surfaces adapting it for reversal andfor right or left.

In testimony whereof we have names to this specification.
